GUIDE: A Quick guide for recruiting a 5* monster

I'm making this guide to be a simple method for people to see how to recruit a 5* monster as a shard vs level.

For a 1% chance to recruit the 5* are

Level 100 shards 7.5
Level 90 shards 7.69
Level 80 shards 7.89
Level 70 shards 8.1
Level 60 shards 8.33
Level 50 shards 8.57
Level 40 shards 8.8
Level 30 shards 9
Level 20 shards 9.375
Level 10 shards 9.6
Level 01 shards 10

since the graph is linear for percentage, all you have to do to work out the shards for a percentage at a level is

(percentage chance you want) X (Shards at the level you are)

E.G. if you want to work out the chance for a 50% success with a level 100 monster

(50) X (7.5) = 375 shards needed

for a 50% chance with a level 1 monster is

(50) X (10) = 500 shards needed

To work out the chance with a number of shards is

_____(Shards you have)_____= Percentage chance
(Shards at the level you are)

Worth noting there's either diminishing returns, or the percentage eventually caps out. I failed to recruit sleipnir with calculated 100% chance, then a second time with ~90% chance.

I think it caps at about 90 - 80% chance

Is this large shards or small shards?

I'm pretty sure it's small shards.
